Proposal: --secret-prefix and key transformation support for infisical run

[SujithThirumalaisamy]

Just wanted to start a discussion around improving infisical run for Terraform workflows

Terraform expects variables to be passed as env vars with the TF_VAR_ prefix and snake_case lowercase keys(common pattern).
Mostly to store secrets we use UPPER_SNAKE_CASE which leads to

• Renaming secrets just for Terraform
• Wrapper scripts to transform env vars
• Extra workarounds for similar workflows

1. Opt-in --secret-prefix flag

   infisical run --secret-prefix=TF_VAR_ terraform apply
   

2. Optional key transformation
   Add a transformation flag to handle naming conventions:

   --transform-secret-key=lowercase|snakecase|kebabcase
   

   DB_PASSWORD → TF_VAR_db_password

Why this helps?

• Seamless Terraform usage or other usecases
• No secret renaming
• No wrapper scripts

Aligns with common IaC + secret management patterns
